Specification forming part 0f Letters Patent No. l 39,856, dated June17, 1873; application tiled February 5, 1873. i

To all whom it may concern.'

Be it known that I, THOMAS H. BEK, of Syracuse, in the county ofOnondaga and State of New York, have invented aMachine for givingPhysio-Balls or other Medicines to Horses, Cows, and other Animals, ofwhich the .followin g is a specification:

My invention relates to an instrument or machine made with a combinationof wood, brass, iron, and rubber, or such other materials as may bedesired, of the form set out and shown in the accompanying drawings, andto be used for giving to horses, cows, or other animals, such medicinesas may be necessary to administer internally.

Figure 1 is a geometrical drawing of the instrument with the plungerthrown forward. Fig. 2 is a sectional drawing of the instrument with theplunger drawn back.

The same letter in each gure in the drawings represents correspondingparts.

A is the body of the instrument, which should be constructed of hardpolished wood, of some of the metals, of any other hard substance, andof any size or length desired, the medium size being one foot and fourinches in length, and in proportion as shown in the drawing. B is arubber band let into and encircling the largest part of the instrumentto prevent the teeth of the animal injuring the instrument during itsuse, and also to furnish an elastic surface next the parts which mustcome in contact with it during its use it may be removed and replaced atpleasure. C is a hole bored into the larger end of the iustruinent, andalso a similar one into the smaller end, the former being a trifle lessthan one-third the length of the instrument in depth, and the latterone-half the length of the instrument in depth, and seven-eighths of aninch in diameter. These two apertures are connected by a small aperturethrough which passes a small rod, E, upon each end of which is fastened,by a screw, a metallic plate, G G,

which works easily in the aperture C and is drawn back, by means of knobH, attached by c a metallic pin to the plate G, whichworks through aslot cut in the side ofthe instrument, as shown by letter F, in Figs. 1and 2. D is a coiled spring fitted into the aperture O, at the small endof the instrument, and should be of sufficient force tothrow, with aquick motion, the plunger composed of rod E and washer G G, forward tothe mouth o f the aperture C. The power of the spring is regulated byplug I, insertedinto the aperture C at the small end of the instrument,and held in its place by pins or screws. I

When the instrument is not in use it should 1 be kept with the plungerthrown forward as shown in Fig. 1, relieving the coiled -spring D frompressure,tliereby preserving its power.

When the instrument is to be used the plunger I should be drawn back bymeans of knob H, compressing the coiled spring D, and fastened backbyturning the knob to the side of 'and catching it into the angle of theslot the rear end, as shown in Fig. 2. The medicine to be administeredshould be made into a small ball or balls, and placed in the aperture (lat the large end of the instrument, which is then inserted into themouth and throat of the animal; the knob H is turned so as to'beloosened from the angle of the slot, the spriii g D throws the plunger GE G forward, and the balls are ejected from the instrument into thethroat.

I claiin- The combination of the rod chambcred at C, furnished withrubber at B, and with the spring plunger-rod, and securing-slot, allarranged as shown and described, and forthe purposes set forth. i
